AppendixC_upperlower

Create a single C++ program that performs the following:

• Intialize the pointer array with the sequence of upper/lower case alphabet pairs, Aa Bb Cc …. Xx Yy Zz. (The first element of the array is Aa; the second element of the array is Bb; etc.)

• Using a for loop, print the contents of the array.

The output should appear exactly as follows with heading and single spaces between the elements:

PRINTING CONTENTS OF ARRAY
==================================
Aa Bb Cc Dd Ee Ff Gg Hh Ii Jj Kk Ll Mm Nn Oo Pp Qq Rr Ss Tt Uu Vv Ww Xx Yy Zz

• Change the program logic to prompt you for a position within the array that coincides with the appropriate letter pair. Your program should be able to duplicate the following session:

Select the number that coincides with the letter pair.
For example, the number 7 should display the pair Gg.

Enter a number between 1 and 26: 4

The number you selected: 4
The pair related to this number: Dd

• Write the code to replace every other element within the original array with a lowercase x. The output should appear exactly as follows with heading and single spaces between the elements:

PRINTING CONTENTS OF ARRAY and adding x to every other element
========================================================
Aa x Cc x Ee x Gg x Ii x Kk x Mm x Oo x Qq x Ss x Uu x Ww x Yy x

• Write the code that will display only the even index elements within the array. The output should appear exactly as follows with heading:

PRINTING CONTENTS OF ARRAY using the MOD option
=====================================================
Even Index Element = 0 Contents of Element within Array is = Aa
Even Index Element = 2 Contents of Element within Array is = Cc
Even Index Element = 4 Contents of Element within Array is = Ee
Even Index Element = 6 Contents of Element within Array is = Gg
Even Index Element = 8 Contents of Element within Array is = Ii
Even Index Element = 10 Contents of Element within Array is = Kk
Even Index Element = 12 Contents of Element within Array is = Mm
Even Index Element = 14 Contents of Element within Array is = Oo
Even Index Element = 16 Contents of Element within Array is = Qq
Even Index Element = 18 Contents of Element within Array is = Ss
Even Index Element = 20 Contents of Element within Array is = Uu
Even Index Element = 22 Contents of Element within Array is = Ww
Even Index Element = 24 Contents of Element within Array is = Yy
